Glad to have you join us :) Not sure I understand what you mean by "covered up". You always want to start your brag book quick pages as with a transparent layer underneath instead of a white background layer. Before you save as a .png you "poke a hole" in the layers for where the picture(s) should go. You can visit the first two sticky threads in this forum
for how to do that if you don't already know. Saving as a png combines all the layers into a flat image so that when someone wants to use it, they can put the pictures under it and they will show through the holes.
